Title: Gas laser tube
Inventor: YASUDA SUSUMU
IPC: H01S3/0975
Filed: 1980-02-22
Abstract: PURPOSE:To give nonelectrodic nature and longer life to a gas laser tube, by mounting more than a pair of outside electrode outside a plasma fine tube and secondary electron radioactive materials inside the tube, and exciting high frequency discharges. CONSTITUTION:A pair of outside electrode 3, 3' is mounted on each outer side of a vacuum outer container 2 which acts as a plasma fine tube containing gaseous laser media 1. A high frequency current is fed to the electrode 3, 3' from a high frequency oscillator 4 to create high frequency excitation. At the time, the secondary electron radioactive materials 11, 11' are mounted inside the plasma fine tube corresponding to the electrodes 3, 3'. When discharge occurs between the electrodes 3, 3' owing to the high frequency excitations, the secondary electrons are discharged from the materials 11, 11' to make uniform the discharges in the laser tube easily and reduce the voltage decrease in the tube and lower the high frequency current to be applied to the electrode 3, 3'. With such an arrangement, because no electrode is contained within, the structure becomes simpler and no gas pressure lowering owing to absorption of gas to electrodes occurs, and longer life on the part of the tube can be realized.

Title: Controlling method of adsorptive type freezer
Inventor: YONEZAWA YASUO
IPC: F25B17/08
Filed: 1989-01-30
Abstract: PURPOSE:To carry out an efficient output control corresponding to a load of a freezer by a method wherein a state of utilization thermal medium at an inlet part of an evaporator is detected and when a utilization load is reduced, adsorption and desorption steps are temporarily stopped for their changing-over and then a low output to be disposed of during a high load operation is applied to the low load. CONSTITUTION:A temperature of a utilization thermal medium before flowing-in into an evaporator 17 is measured by a temperature sensor 27. Then, in case that its result is lower than a predetermined temperature and it is judged as a low load, opening or closing operation of all valves V1 to V8 are stopped at their present states so as to stop the changing-over operation for the adsorption and desorption steps. With such an operation as above, a freezing output is not changed over even at a changing-over between the adsorption and desorption and irrespective of a scarce input, a low output is continued to discharge. Then, when the output is too low and can not be accommodated for the low load at the utilization, a temperature of the temperature sensor 27 is increased more than a predetermined temperature again and this is displayed. At this time, the opening or closing operation of the valve is started in order to start the adsorbing and desorption operation, and a normal output is attained.
